Answer:
x= 1
y= -1
Hope this helps!
Step-by-step explanation:
1 Substitute y=3x−4 into y=x-2
3x-4=x-2
2 Solve for x in 3x-4=x-2
x=1
3 Substitute x=1 into y=3x-4
y=-1
4 Therefore,
x=1
y=-1
Answer:
$80.75
Step-by-step explanation:
From the question, we are given the following parameters
Amount borrowed (principal)=$3800
Time=3 months =1/4 years
Rate = 8.5%
Required
Interest paid by the man
Using the simple interest formula;
SI= Principal*Rate*Time/100
SI=3800*8.5*0.25/100
SI=38*8.5*0.25
SI=$80.75
Hence the man paid $80.75 for the use of the money

I could be wrong but i graphed it out and 9 is C , 10 is A , and 11 is C Hopefully it's right
Answer:
W = 9.33 grams
X = 4.67 grams
Step-by-step explanation:
Given;
Mass of Z to be made = 14 grams
Composition of Z
W:X:Y = 2:1:3
To make 6 grams of Y requires 4 grams of W and 2 grams of X
Composition of Y (for 6grams)
W:X = 4:2 = 2:1
Substituting the composition of Y to Z
Z = W:X:Y = 2:1:3
Z = W:X:W:X = 2:1:2:1
summing them up, we have;
Z = W:X = 4:2 = 2:1
Since the final mixing ratio for W and X are 2:1, to make 14 grams of Z, we need;
W = 2/3 × 14grams = 28/3 grams
W = 9.33 grams
X = 1/3 × 14grams = 14/3 grams
X = 4.67 grams
